Description

本発明は、廃木材および汚染土壌を用いて土壌改良剤を製造する廃棄物利用土壌改良剤製造システムに関する。   The present invention relates to a waste-use soil improver manufacturing system that manufactures a soil improver using waste wood and contaminated soil.

工場跡地あるいは事業所跡地等の土壌には、例えば鉛、砒素、６価クロム等の重金属類やトリクロロエチレン等の有機化合物が土壌汚染物質として含まれていることが多い。このような土壌汚染物質は土壌汚染対策法により特定有害物質に指定されており、土地所有者は汚染土壌から汚染物質を除去することが義務付けられるようになった。
一方、家屋の解体現場で発生する廃木材も建築廃材リサイクル法によって再資源化が義務付けられるようになった。建築廃木材の他にも街路樹の剪定樹枝や間伐材も再資源化が望まれるが、これらの廃木材はチップ化したものを公園や遊歩道に敷詰めたり堆肥化したりするなどの限定的な用途の開発しか進んでおらず、依然として焼却処分されることが多かった。 For example, heavy soils such as lead, arsenic, and hexavalent chromium, and organic compounds such as trichlorethylene are often contained in soils such as factory sites or business sites as soil pollutants. Such soil pollutants are designated as specific hazardous substances by the Soil Contamination Countermeasures Law, and landowners are now obligated to remove pollutants from contaminated soil.
On the other hand, waste wood generated at the site of demolishing houses is now required to be recycled by the Building Waste Recycling Law. In addition to building waste wood, pruning branches of roadside trees and thinned wood are also desired to be recycled, but these waste wood is limited to chippings that are laid down in parks and promenades or composted. Only the development of the application was advanced, and it was still often incinerated.

汚染土壌を改質処理する方法としては、図２に示されるように、混練機２０と、攪拌翼２２を有する水蒸気処理機２１とからなる処理装置を用い、汚染土壌と廃木材等の廃棄物とが組み合わされた被処理物を、混練機２０内で石灰材およびシリカ材を加えてＣａＯ量を２．５〜３５重量％、ＳｉＯ2量を２５〜６５重量％に調整し、０．２５〜１５重量％の還元材を溶解させた水でファニキュラー状態（粒子表面全体が液体でぬれ、数百μｍ〜数十ｍｍの粒状体となっている状態）に混練した後で、水蒸気処理機２１内で攪拌しながら４０〜１００℃で０．５〜２４時間蒸気処理することによって、汚染土壌に含まれる汚染物質を還元反応と水和反応によって安定化する方法が知られている（特許文献１参照）。 As shown in FIG. 2, as a method for modifying the contaminated soil, a processing apparatus including a kneader 20 and a steam processor 21 having a stirring blade 22 is used, and waste such as contaminated soil and waste wood is used. In the kneading machine 20, the lime material and the silica material are added in the kneading machine 20 to adjust the CaO amount to 2.5 to 35% by weight and the SiO 2 amount to 25 to 65% by weight. Steam mixer after kneading into water in which ˜15% by weight of reducing material is dissolved in a funicular state (the whole particle surface is wet with a liquid and is in the form of several hundred μm to several tens of mm) A method is known in which a pollutant contained in contaminated soil is stabilized by a reduction reaction and a hydration reaction by steam treatment at 40 to 100 ° C. for 0.5 to 24 hours with stirring in the apparatus 21 (Patent Document). 1).

しかしながら、特許文献１に記載の廃棄物処理方法は、汚染土壌内の汚染物質を還元反応と水和反応によって安定化を図るものであり、汚染物質が完全に無害化されたとはいえない。
また、特許文献１に記載の廃棄物処理方法で安定化処理された処理物は、高付加価値の資源物として有効活用され得る程の機能性を備えてはいない。
さらには、この廃棄物処理方法では、被処理物のＣａＯ量、ＳｉＯ2量、還元材量や蒸気処理の諸条件を調整する必要があり、汚染土壌や廃棄物の性状の変化に対応して添加物の量を調整しなければならないとともに、被処理物をファニキュラー状態に保つためには処理設備に高度な制御装置等を備える必要があった。
特開２００４−１６７３７４号公報 However, the waste treatment method described in Patent Document 1 stabilizes the pollutants in the contaminated soil by a reduction reaction and a hydration reaction, and it cannot be said that the pollutants are completely detoxified.
In addition, the processed product stabilized by the waste processing method described in Patent Document 1 does not have functionality that can be effectively used as a high-value-added resource.
Furthermore, in this waste treatment method, it is necessary to adjust the CaO amount, SiO 2 amount, reducing material amount and steam treatment conditions of the object to be treated, in response to changes in the properties of contaminated soil and waste. The amount of the additive had to be adjusted, and in order to keep the object to be processed in the funicular state, the processing equipment had to be equipped with an advanced control device or the like.
JP 2004-167374 A

本発明は、従来の廃棄物処理方法における上記問題を解決するものであって、汚染土壌および廃木材を完全に無害化し、処理物を高付加価値の資源物として有効活用可能で、高度な制御の不要な簡易な装置で設備を構成できる廃棄物利用土壌改良剤製造システムを提供することを目的とする。   The present invention solves the above-mentioned problem in the conventional waste treatment method, completely detoxifies contaminated soil and waste wood, and can effectively use the treated product as a high-value-added resource, and provides advanced control. It aims at providing the waste improvement soil improvement agent manufacturing system which can comprise an installation with the simple apparatus which is unnecessary.

本発明の廃棄物利用土壌改良剤製造システムは、廃木材および汚染土壌を用いて土壌改良剤を製造する廃棄物利用土壌改良剤製造システムであって、廃木材を炭化処理する炭化炉と、炭化炉の後段に配置された二次燃焼炉と、二次燃焼炉で発生した高温ガスを熱源として汚染土壌を加熱処理する土壌加熱炉とを備え、廃木材を炭化処理することにより炭化炉で得られた炭化物と、汚染土壌を加熱処理することにより土壌加熱炉で得られた浄化土壌とを混合して土壌改良剤を得ること、上記課題を解決している。   A waste-use soil improver production system of the present invention is a waste-use soil improver production system for producing a soil improver using waste wood and contaminated soil, a carbonization furnace for carbonizing waste wood, It is provided with a secondary combustion furnace located at the rear stage of the furnace and a soil heating furnace that heats the contaminated soil using the high-temperature gas generated in the secondary combustion furnace as a heat source, and carbonizes the waste wood. The above-mentioned problems are solved by mixing the obtained carbide and the purified soil obtained in the soil heating furnace by heating the contaminated soil to obtain a soil conditioner.

本発明の廃棄物利用土壌改良剤製造システムでは、廃木材を炭化処理したときに発生する乾留ガスを二次燃焼炉で高温に加熱し、これを熱源として汚染土壌に含まれる汚染物質を高温に加熱して熱分解することで、汚染土壌を完全に無害化できる。さらに、炭化炉で得られた炭化物と土壌加熱炉で得られた浄化土壌とを混合することで、資源化物である土壌改良剤を得ることができる。この土壌改良剤は、清浄であり、かつポーラス状を呈する炭化物を含むため、微生物の定着性がよく有効な性質を有する。
炭化炉および土壌加熱炉の形式は、特に限定されないが、装置構成の簡易さや高度な制御の不要等を考慮すると、ロータリーキルン式炉であることが望ましい。 In the waste soil improvement agent manufacturing system of the present invention, the carbonization gas generated when carbonizing waste wood is heated to a high temperature in a secondary combustion furnace, and this is used as a heat source to increase the contaminant contained in the contaminated soil to a high temperature. By heating and pyrolyzing, the contaminated soil can be completely detoxified. Furthermore, by mixing the carbide obtained in the carbonization furnace and the purified soil obtained in the soil heating furnace, a soil improver that is a resource product can be obtained. Since the soil conditioner is clean and contains a porous carbide-like carbide, it has an effective property with good microbial colonization.
The types of the carbonization furnace and the soil heating furnace are not particularly limited, but it is preferable that the rotary kiln type furnace is used in consideration of the simplicity of the apparatus configuration and the need for advanced control.

本発明の廃棄物利用土壌改良剤製造システムでは、汚染土壌および廃木材を完全に無害化し、処理物を高付加価値の資源物として有効活用可能で、高度な制御の不要な簡易な装置で設備を構成できる。   In the waste-use soil improver manufacturing system of the present invention, the contaminated soil and waste wood are completely harmless, the treated product can be effectively used as a high-value-added resource, and equipment is installed with a simple device that does not require advanced control. Can be configured.

以下、本発明に係る廃棄物利用土壌改良剤製造システムを図面に基づいて説明する。
図１は、本発明の一実施の形態である廃棄物利用土壌改良剤製造システムの概略構成図である。同図において、本実施形態の廃棄物利用土壌改良剤製造システム１は、廃木材Ａを炭化処理する炭化炉２と、炭化炉２の後段に配置した二次燃焼炉３と、汚染土壌Ｂを加熱処理する土壌加熱炉４とから構成される。なお、廃棄物利用土壌改良剤製造システム１内で発生する排ガスは、可燃物Ｆを焼却処理したときに発生する排ガスを処理する排ガス処理ラインの二次燃焼炉１１に送られる。 Hereinafter, the waste utilization soil improvement agent manufacturing system which concerns on this invention is demonstrated based on drawing.
FIG. 1 is a schematic configuration diagram of a waste-use soil conditioner manufacturing system according to an embodiment of the present invention. In the figure, a waste-use soil improving agent production system 1 according to the present embodiment includes a carbonization furnace 2 that carbonizes waste wood A, a secondary combustion furnace 3 that is disposed downstream of the carbonization furnace 2, and a contaminated soil B. It is comprised from the soil heating furnace 4 to heat-process. In addition, the exhaust gas generated in the waste-use soil improver manufacturing system 1 is sent to the secondary combustion furnace 11 of the exhaust gas processing line that processes the exhaust gas generated when the combustible F is incinerated.

炭化炉２はロータリーキルン式の加熱炉であり、建築廃木材や街路樹の剪定樹枝や間伐材といった廃木材Ａを６００〜８００℃に加熱して炭化処理するものである。この炭化炉２で炭化処理された廃木材Ａは炭化物Ｃとなり、このとき炭化炉２で発生した乾留ガスは、ダイオキシン対策のため、二次燃焼炉３に導入され、ここで８５０℃以上に昇温されて無害化される。   The carbonization furnace 2 is a rotary kiln type heating furnace, and heats the waste wood A such as waste wood from construction, pruned branches of roadside trees, and thinned wood to 600 to 800 ° C. to perform carbonization. Waste wood A carbonized in the carbonization furnace 2 becomes carbide C, and the dry distillation gas generated in the carbonization furnace 2 at this time is introduced into the secondary combustion furnace 3 as a countermeasure against dioxins, where the temperature rises to 850 ° C. or higher. Heated and detoxified.

炭化炉２で発生した乾留ガスは６００〜８００℃の熱量を有しているため、二次燃焼炉３では乾留ガスを僅かのエネルギーで８５０℃以上に昇温することが可能である。
二次燃焼炉３で昇温された乾留ガスは高温ガスとなり、汚染土壌Ｂを土壌加熱炉４で加熱処理するときの熱源として土壌加熱炉４に導入される。
土壌加熱炉４はロータリーキルン式の加熱炉であり、汚染土壌Ｂを６００〜８００℃で加熱処理するものである。この土壌加熱炉４で加熱処理された汚染土壌Ｂは浄化土壌Ｄとなり、このとき土壌加熱炉４で発生した排ガスは、可燃物Ｆを焼却炉１０で焼却したときに発生する排ガスを処理する排ガス処理ラインの二次燃焼炉１１に送られて無害化される。 Since the dry distillation gas generated in the carbonization furnace 2 has a heat quantity of 600 to 800 ° C., the secondary combustion furnace 3 can raise the dry distillation gas to 850 ° C. or more with a little energy.
The dry distillation gas heated in the secondary combustion furnace 3 becomes a high-temperature gas, and is introduced into the soil heating furnace 4 as a heat source when the contaminated soil B is heat-treated in the soil heating furnace 4.
The soil heating furnace 4 is a rotary kiln type heating furnace, and heats the contaminated soil B at 600 to 800 ° C. The contaminated soil B heat-treated in the soil heating furnace 4 becomes purified soil D, and the exhaust gas generated in the soil heating furnace 4 at this time is exhaust gas for treating the exhaust gas generated when the combustible F is incinerated in the incinerator 10. It is sent to the secondary combustion furnace 11 of the processing line and rendered harmless.

炭化炉２で得られた炭化物Ｃと土壌加熱炉４で得られた浄化土壌Ｄを混合することで土壌改良剤Ｅを製造する。浄化土壌Ｄは高温加熱によって完全に無無害化されているので、再利用するのに支障がない。また、炭化物Ｃはポーラス状を呈しており、微生物の定着性がよいため、両者の混合材である土壌改良剤Ｅは高付加価値の資源物として有効活用可能である。   The soil improving agent E is manufactured by mixing the carbide C obtained in the carbonization furnace 2 and the purified soil D obtained in the soil heating furnace 4. Since the purified soil D is completely detoxified by high temperature heating, there is no problem in reusing it. In addition, since the carbide C has a porous shape and has good microbial fixation, the soil improver E, which is a mixture of both, can be effectively used as a high-value-added resource.

土壌加熱炉４は二次燃焼炉３で８５０℃以上に昇温されて高温ガスとなった乾留ガスを熱源として汚染土壌Ｂを加熱処理する構成となっているため、ランニングコストを低減することができる。
炭化炉２および土壌加熱炉４がそれぞれロータリーキルン式炉であるので装置構成が簡易で高度な制御等は必要ない。また、炭化炉２および土壌加熱炉４は廃木材Ａや汚染土壌Ｂの被処理物を高温で加熱処理できるので、被処理物を確実に無害化することができる。 Since the soil heating furnace 4 is configured to heat the contaminated soil B using the dry distillation gas that has been heated to 850 ° C. or higher in the secondary combustion furnace 3 to become a high-temperature gas as a heat source, the running cost can be reduced. it can.
Since each of the carbonization furnace 2 and the soil heating furnace 4 is a rotary kiln type furnace, the apparatus configuration is simple and no advanced control or the like is required. Moreover, since the carbonization furnace 2 and the soil heating furnace 4 can heat-treat the waste wood A and the contaminated soil B to be treated at a high temperature, the to-be-treated object can be reliably rendered harmless.

本実施形態の廃棄物利用土壌改良剤製造システム１は、単独で処理システムを構築することも可能であるが、総合的な廃棄物処理設備の一部として構成してもよい。例えば、図１に示すように、可燃物Ｆを燃焼するストーカ式の焼却炉１０と、焼却炉１０で発生した排ガスを加熱する二次燃焼炉１１と、二次燃焼炉１１から排出された排ガスの熱エネルギーを回収する廃熱ボイラ１２と、廃熱ボイラ１２からの排ガスを冷却するガス冷却塔１３と、ガス冷却塔１３から排出された排ガス中のダストを捕集するバグフィルタ１４と、バグフィルタ１４からの排ガスを大気放出する煙突１５とからなる排ガス処理ラインに、廃棄物利用土壌改良剤製造システム１を併設して総合的廃棄物処理設備を構成してもよい。   Although the waste utilization soil improvement agent manufacturing system 1 of this embodiment can also construct | assemble a processing system independently, you may comprise as a part of comprehensive waste processing equipment. For example, as shown in FIG. 1, a stoker-type incinerator 10 that combusts combustibles F, a secondary combustion furnace 11 that heats exhaust gas generated in the incinerator 10, and exhaust gas discharged from the secondary combustion furnace 11. A waste heat boiler 12 that collects the heat energy of the gas, a gas cooling tower 13 that cools the exhaust gas from the waste heat boiler 12, a bag filter 14 that collects dust in the exhaust gas discharged from the gas cooling tower 13, and a bug An integrated waste treatment facility may be configured by adding the waste soil improvement agent production system 1 to the exhaust gas treatment line including the chimney 15 that releases the exhaust gas from the filter 14 to the atmosphere.

このような構成によると、土壌加熱炉４で発生した排ガスは二次燃焼炉１１で高温に加熱された後、廃熱ボイラ１２、ガス冷却塔１３及びバグフィルタ１４を経て煙突１５から大気中に放出される。したがって、排ガス処理設備を集約できると共に土壌加熱炉４から排出される排ガス中の熱エネルギーを廃熱ボイラ１２やガス冷却塔１３で回収できるため、設備コストとランニングコストの両方を低減することができる。
なお、廃熱ボイラ１２で回収された熱エネルギーは大規模発電機１６に供給される。また、焼却炉１０で発生した焼却灰Ｇは、大規模発電機１６から供給される電気エネルギーにより駆動する電機式溶融炉（図示せず）で溶融処理される。 According to such a configuration, the exhaust gas generated in the soil heating furnace 4 is heated to a high temperature in the secondary combustion furnace 11, and then passes through the waste heat boiler 12, the gas cooling tower 13, and the bag filter 14 from the chimney 15 to the atmosphere. Released. Accordingly, the exhaust gas treatment facilities can be consolidated and the heat energy in the exhaust gas discharged from the soil heating furnace 4 can be recovered by the waste heat boiler 12 or the gas cooling tower 13, so that both the facility cost and the running cost can be reduced. .
The thermal energy recovered by the waste heat boiler 12 is supplied to the large-scale generator 16. Further, the incineration ash G generated in the incinerator 10 is melted in an electric melting furnace (not shown) that is driven by electric energy supplied from the large-scale generator 16.
